Ej. Atkinson et al., SYNTHESIS OF TOTALLY RIGID COVALENTLY-LINKED BIS-PORPHYRIN SYSTEMS FOR STUDYING LONG-RANGE ELECTRON-TRANSFER AND ENERGY-TRANSFER PROCESSES, Tetrahedron letters, 34(38), 1993, pp. 6147-6150
The synthesis of novel rigid covalently linked bis-porphyrin systems,
3 - 5, and the monoporphyrin model, 6, is described. The synthetic str
ategy entails formation of o-phenylenediamine units, 11, and their rea
ction with the dioxotetraphenylchlorin, 12.
